swam?- BAG-FRAME BRACKET.

Application filed November 26, 1923. Serial No. 676,921.

T all whom it may concern.

Be it known that I, AUoUs'r J. PETRIE, a citizen of the United States,residing at West Allis, county of Milwaukee, and State of Wisconsin,have invented new and useful Improvements in Bag-Frame Brackets, ofwhich the following is a specification.

My invention relates to improvements in bag frame brackets, such as areemployed to connect the lock-side band, or hasp-side band, with theirassociated inlay bands.

Brackets for this purpose have been used for many years and such useinvolves no specific or diflicult problem in the-manufacture of handsewed traveling bags. But the ordinary bag frame bracket interferes withmachine stitching operations and modern production requirements call forthe use of sewing machines for stitching the bags to the frame coversand linings. This has led to the use in some cases of specially formedbrackets having surfaces adapted to deflect the awl or needle of asewing machine when it strikes a bracket, whereby the stitchingoperation may proceed without cessation.

The object of my invention is to provide means whereby inexpensivebrackets may be formed byblanking out pieces of sheet metal andsimultaneously punching out their central portions to form stitchreceiving apertures flanked on both sides by narrow connecting members,the openings being sutficient in size to ensure stitching operationsbetween the connecting members, and the form of the openings beingsuchas to provide struts of maximum strength in proportion to their widthalong the stitching line, thereby making it possible to utilize strutswhich are sufficiently thin or narrow where they cross the stitchingline to avoid catching or holding the tubular awl with which sewingmachines are equipped for such purposes and which passes throughthegoods in advance of the needle.

In the drawings:

Figure 1 is a side view of a bag frame equipped with my improvedbrackets.

Figure 2 is a sectional view drawn on line 2-2 of Figure 1.

Figure 3 is .a perspective view showing the fragments of a lock-side or'hasp-side band and associated inlay with the covering applied-over oneofthe connecting'brackets 4 I and stitched in position across thebracket.

Figure 4 1s a sectional view on line 44 of Figure 3. I

Like parts are identified by the same reference characters throughoutthe several views. a i

In Figure 1 a bagframe is illustrated which, in its generalcharacteristics, conforms to ordinary practice,-,the lock-side band 1,associated inlay band 2, hasp-side band 3, and associated inlay band 4being of ordinary construction.

The lockside band 1 and the hasp-side band 3 are, however,connected withtheir associated inlay bands 2 and 4 respectively,

by brackets 5 substantially half-elbo'wed at 6 and 7 and provided withapertures'S in the portion between the points '6 and v7. These apertures8 are of a size or diameter to nearly sever the bracket along a lineparallel tothe connecting bands and substan= tially midway between them.The apertures are preferably'circular in form so that they can beproduced by an ordinary punch simultaneously with the operation ofblanking.

out'the bracket. This circular form of the aperture is also preferredfor the reason that it allows the bracketlto have a maximum strengthconsistent with the desired purpose of allowing unobstructed, machinestitching across the bracket.

It will be observed that abracket, aperture'd-as above described formssubstantially a duplex connection between the associated bandsi. e.aconnection composed of two arms, each of which progressively widens fromits central portion toward the respective bands,the portions 64, a andb, b being of considerably greater width than the portions 0, c. Saidportions 0, 0 cross the stitching line and they are too narrow tomaterially obstruct the awl of the sewing machine. If struck by the awl,the latter vibrates sufficiently to dislodge and pass on one side or theother of the portions 0, c

which it strikes.

The openings 8 have a greater diameter along the line ofstitching thanthe distance between two successive operations of the needle, thediameter beingsuflicient to allow two stitching operations to take placebeloo tween the two connecting arms of th bracket-i. e.-between theportions 6 0 o the bracket.

With the above described bracket construction, each connecting arm ofeach bracket has its portion 0 or c virtually embraced or surrounded bythe covering material, which is held firmly to it by stitches on eachside in close proximity thereto. This not only re-enforces the bracketand prevents the thin arms a, c from being distorted or bent out o1place, but it also allows the covering to be held as firmly and smooth--ly in position over the brackets as in any other portion. Intact, theconnection of the covering isstr-onger' at the brackets than at anyother points along the line of stitching because of the plurality oftransverse nietallicarms comprising the portions 0, c on the bracket.

1 The end, portions of the bracket being in substantially half-elbowedconnection with the central portion, it is obvious that the inlay bandswill'be outwardly offset from tne lock-side and hasp-side bandsrespectively.

he needle of the sewing machine operates substantially perpendicularlyto the central portions of the brackets.

I claim: I

L A connecting bracket for bag it'rame bands, comprising a piece ofsheet metal having end portions in substantially haltelbowed relation tothe central portion and having a central aperture of sutficient size tonearly sever the central portion of the bracket leaving the end portionsconnected by two thin armsot insuliicient Width to obstruct the awl andneedle oi the sewing machine. 7

2. A bag frame bracket comprising a piece of staniped sheet metal havingend portions adapted to be secured to the associated bandsof theframe-,and an inte mediate portion provided with an aperture ofsufficient size to nearly sever the end position, each of said bracketshaving its central portion provided wtih an aperture of a size to nearlysever the bracket at the points where they cross the stitching lines.each of said brackets being connected with the covering by a stitchedthread passing through the aperture and through the material on bothsides of the bracket.

In a device of the character described a bracket adapted for attachmentat its ends to bag frame elements and provided intermediate its endswith aportion lying substantially entirely in a given plane; saidportion being provided with an aperture reaching almost to its margins,whereby the bracket portions intermediate such aperture and the marginof the bracket are so re duced in width as not to interfere materlallywith a stitching operation conducted transversely of the bracket andacross said aperture.

5. In a device of the character described, a bracket having its endportions substantially at right angles to each other and having anintermediate diagonal portion lyingsubstantially altogether in oneplane, said intermediate portion. being provided with' an apertureextending almost to its margim whereby to leave a very narrow rimadaptcd. not to interfere materially with a stitching operationconducted transversely of said bracket. 1
